摘要： A method for diagnosing a failure of an EGR circuit of an engine including an EGR exchanger, an EGR valve, a bypass duct of the EGR exchanger, and a bypass flap arranged upstream from the EGR exchanger and the bypass duct to adjust a proportion of exhaust gases flowing therethrough. The EGR circuit can be activated according to a cooled mode, in which the flap is shut, or according to a bypass mode, in which the flat is open. The method carries out, during a diagnosis phase, two activations of the flap, and measures an average of variations of the EGR gas temperature at an outlet of the EGR exchanger during the diagnosis phase.

摘要： A method for diagnosing a failure of an EGR circuit in an engine that includes an EGR exchanger, an EGR valve, an EGR exchanger bypass duct, and a bypass flap located upstream from the EGR exchanger and the bypass circuit in order to adjust the proportion of exhaust gases flowing therethrough. The EGR circuit can be activated in a cooled mode in which the flap is shut and in a bypass mode in which the flap is open. The method estimates the temperature of the exhaust gases at the outlet of the EGR exchanger when the EGR circuit is in the bypass mode.

摘要： A mechanical greasing apparatus is reservoir, for lubricating heavy machinery. The apparatus comprises a grease reseroivr, a piston cylinder arrangement coupled to the grease reservoir, which is adapted to deliver a continuous flow of grease, and a grease pipe connected to the piston cylinder arrangement to receive the continuous flow of grease from the piston cylinder arrangement. The piston cylinder arrangement is usually operated by an electric power motor.
